Assume hip-width stance facing wall about three to four feet away
Fully extend arms against wall and form 45-degree angle with body
Quickly drive right knee up as high as possible and hold for two seconds
Drive right foot down onto ground underneath hips
Repeat with left leg
Perform sequence in continuous fashion for specified time
Sets/Duration/Rest: 2-4x10-15 seconds/Arm Action
Adaptation: Once you feel comfortable with the technique, perform the same sequence without the pause at the top. It should be an all-out sprint against the wall. Apply the same sets and reps.
Coaching Points: Place hands at chest level and shoulder-width apart against wall // You should be able to draw a straight line from your ears down to your hips and ankles // Your foot and toes should be dorsi-flexed (turned upward in the top position) // Keep toe underneath knee and heel underneath butt in the top position
